Specification of Letters Patent.

Patented Nov. 12,1912.

Original application filed November 23, 1909, Serial No. 529,514.Divided and this application filed April 2, 1910. Serial No. 553,139.

To all whom it may concern:

Be it known that I, JOHN F. KELLY, a citizen of the United States,residing at Trenton, county of Mercer, State of New Jersey, haveinvented certain new and useful Improvements in Soil-Pipe Connectionsfor Water-Closet Bowls; and I do hereby declare the following to be afull, clear, and

exact description of the invention, such aswill enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to water closet bowls, and more especially to thesoil pipe connections of the same, the object of the invention being theprovision of an improved soil pipe connection by which the bowl and soilpipe are firmly and reliably locked together and supported with relationto each other without liability of leakage.

The novel features of the invention will appear more clearly from thefollowing description and claims.

In the accompanying drawing, the single view is a front elevation,partly in section, of a bowl having a soil pipe connection embodying theinvention.

In the drawing, the bowl 3 is shown as having an extension 12 below thefloor line and a base flange 11 above said extension,

but I wish it to be understood that the improved soil pipe connectionforming the subject matter of my invention may be used with bowls ofmany other types. In the embodiment illustrated, the usual threadednipple 8 which extends down from the lower surface of the bowl (in thiscase, from the extension 12) is located at quite some distance below thefloor line, but this is likewise a non-essential feature.

A collar or sleeve 14 is screwed on the threaded nipple S, and saidsleeve is surrounded with a certain amount of clearance by the soil pipe9. The latter is formed at its upper end with a lateral flange 15 havingan upstanding rim 16 and on the upper surface of said flange andretained in place by the rim 16 is a gasket or packing 17 of suitablematerial, such gasket being perforated to pass over the sleeve 14 andmake a tight fit therewith. On top of the gasket 17 is placed a disk orplate 18 that is perforated to receive bolts 19, the threaded lower endsof which are screwed into the soil pipe flange 15, as shown, the boltsbeing headed at their upper ends and passed through the base flange 11of the bowl. The bolts 19 are provided with fixed collars or shoulders20 to abut against the upper surface of the plate 18, and the heads 21of said bolts are preferably incased in cap nuts 22 that are screweddown on the base flange 1n a manner well known in the art.

By constructing the connection in the manner described, it is possible,by screwing the bolts 19 as far as possible in the soil pipe flange, toforce the shoulders or collars 20 of the bolts into tight contact withthe plate 18 and at the same time to move the soil pipe and bowl towardeach other, the gasket or packing 17 being compressed by the plate 18 tosuch an extent that its inner edge will make gas and water tight contactwith the smooth outer surface of the sleeve 14k. In this way, a hermeticclosure is effected between the soil pipe and the discharge end of thebowl and the bowl and soil pipe are firmly connected to each other.

It is evident that the connection described is capable of variousmodifications and that other features of the structure may also bemodified without departing from the spirit of the invention.

What I claim is 1. The combination of a water closet bowl having adepending nipple, a soil pipe embracing the nipple, a gasket seated onthe upper end of the soil pipe, around the nipple, a plate resting onthe gasket, and means which compresses the gasket between the plate andsoil pipe and also connects the soil pi e to the bowl.

2. The combination with a water closet bowl having a depending nipple,of a sleeve screwed on the nipple, a soil pipe surrounding the sleeve, agasket seated on the upper end of the soil pipe, around the sleeve, aplate resting on the gasket, and means which compresses the gasketbetween the plate and soil pipe and connects the soil pipe and the bowl.

3. The combination with a water closet bowl having a laterally directedbase flange, and a nipple below the base flange, of a soil pipesurrounding the nipple, a gasket seated on the upper end of the soilpipe and also surrounding the nipple, a plate resting on the gasket, andbolts passing through the base flange and soil pipe and operative tocompress the gasket and connect the soil pipe and the bowl.

4. The combination with a water closet bowl having a laterally directedbase flange, and a nipple below the flange, of a sleeve threaded on thenipple, a soil pipe embracing the nipple and having an outstandingflange, a gasket seated on said flange, a plate on top of the gasket,and bolts passing through the base flange and threaded into the flangeof the soil pipe to connect the soil pipe and the bowl, said boltshaving shoulders to abut against said plate and thereby compress thegasket into tight contact with said sleeve. g

5. The combination with a water closet bowl having a laterally directedbase flange,

and a nipple below the base flange, of a soil pipe surrounding thenipple, a flat lateral flange on the upper end of the soil pipe, agasket seated directly on the upper surface of said flange, around thenipple, and bolts connecting the soil pipe flange to the base of thebowl and having means to compress said gasket against the soil pipeflange.

In testimony whereof I' aflix my signature, in presence of twowitnesses.
